In the nearly three years since a gunman killed 17 people at Marjory Stoneman Douglas High School in Parkland, survivors and families of those who died have grieved their losses, launched gun-control and school-safety movements, and inspired changes to gun laws in states across the country.
They have also battled misinformation and, to this day, continue to speak out against harmful conspiracy theories calling the February 14, 2018 massacre a hoax. Most recently, they've taken on Marjorie Taylor Greene, the Parkland-denying, QAnon-credulous Republican congresswoman who apparently believes the shooting was a "false flag" and who was caught on camera harassing student activist David Hogg.
